Hello lyt,
There is a configuration so that you can get triple monitor configuration in your system. The configuration is the following:
DisplayPort* + DisplayPort + HDMI* or DVI or VGA or DisplayPort or Built-in Display2
DisplayPort or HDMI or DVI or VGA + DisplayPort or HDMI or DVI or VGA + Built-in Display3
DisplayPort or HDMI or DVI or VGA or Built-in Display2 + DisplayPort or HDMI or DVI or VGA + Intel® Wireless Display (Intel® WiDi)
You can check this information at the following link:

It is important to mention that using adapters may interfere in the signal causing problems that can affect the multiple monitor configurations.
